Hello.
I need to fit a new radiator in the kitchen. I have a Baxi Combi HE which is big enough for the job. The flow and return from the boiler (also in the kitchen) is 22m going to a 4x 8mm manifold for each leg. I want to tee off on the 22m legs for the new circuit (only 4m long).
My plan is to leave all bleed valves closed and to open the drain cock to drain the pipework below the boiler. I would imagine that most of the water will remain in the pipes. Then I can use a compression tee on each leg. Once the new radiator is connected, I intend to use the filling loop to fill the new rad until the pressure is back up. Then use the bleed valves to get rid of the air.
I am hoping that I won't have to add any more Sentinel as it was only done about 4 months ago when the boiler was replaced.
So my question is, is there a flaw in my plans? Will I really be able to hold the water in the system whilst I fit a pair of tees? And will I have to top up the inhibitor and if so, can I do this first by pouring some into the new rad by removing the bleed valve?
I hope this makes sense and what I'm trying to do isn't really stupid...
